Annie Curtis and Dr. Peter Paton at the University of Rhode Island have just published a paper titled "Assessing detection probabilities of larval amphibians and macroinvertebrates in isolated ponds" in the journal Wetlands. Although they describe the utility of their results within the framework of monitoring the ecological condition of isolated aquatic habitats such as vernal pools based on observations in 36 Rhode Island ponds, there are clear implications for my ambition to document community assembly in the Heiberg constructed pools. Curtis and Paton add a great deal of temporal resolution to the general phenological patterns described in the seminal paper by Wiggins et al. in 1980, "Evolutionary and ecological strategies of animals in annual temporary pools." The waxing and waning of detection probabilities for 8 amphibian species and 10 macroinvertebrate families between mid-May and the end of July are nicely portrayed in Figures 2 and 3. Also, the influence (or lack thereof) on detection probabilities of abiotic and habitat structure variables such as water temperature, pond depth, aquatic vegetation, and woody debris are instructive for designing a sampling protocol in the present and as habitat develops in the future.
